180, 180, 180!!
She has checked out of your marriage. And for all intents and purposes, has destroyed it by chatting with other men right in front of you.
She has shown you that she has no intention of wanting to save your marriage. And don't mistake her "confusion" for anything else than wanting to test-drive another man while you stay at home and babysit. You are Plan B. Don't settle for that!
I'm being blunt here, but you need to get your balls back. Value yourself. You are the prize. You can't "save" her. She has to do that for herself. And even then it's no guarantee that she'll pick you. So work on yourself and take care of you.
What you are doing is pain shopping. At the very least, you are playing Infidelity Police and all it does is re-traumatize you.
When you get the urge to this, focus on something you can do for yourself. Run, lift weights, under-water basket weaving...whatever.
These checking behaviors show that you are still focused on saving the marriage. Which is dead. You're addicted to "hopium". You need to accept in your mind that she is not the person you fell in love with. She probably never was. And she has moved on.
Look, I get it. I really do. My XWW checked out of my marriage a few years before I found out she was cheating. I lived on hopium for a while, doing the Pick Me dance. I wasted years eating up any crumbs she would toss my way, thinking that all marriages go through phases like this.
She wants to day other men? Fine. She can do so, but not as your wife.
I highly recommend on pushing hard for the divorce. Lawyer up and file. Today. Don't wait until after the holidays because you think it'll be much easier. Don't delay the inevitable. Remember, if she somehow pulls her head out of her ass and decides she wants to try and do the work (highly unlikely) then you can call off the D process. But don't accept another second of how she is disrespecting you.
There's a thread here in the "I Can Relate" forum about codependency. You should give it a read. Good luck.
